Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

NOTE: Operating ranges define the limits for functional operation and parametric characteristics of the device. Note that the functionality
of the chip outside these operating ranges is not guaranteed. Operating outside the recommended operating ranges for extended
periods of time may affect device reliability.
